Electrical Engineering
The expertise of GIBB's Electrical Engineering team covers the full range of internal and external electrical systems, including:
- Generation plant and standby power generation
- MV and LV distribution systems and switching arrangements
- Pumpstations
- Illumination
- “Clean” electrical supplies and UPS
- Control of interference
- Metering and sub-metering
- Elevator and escalator installations
- Earthing and lightning protection
- Rail electrification
- Rail signalling
- Electronic systems, i.e.
Radio and TV reception/distribution systems, public address and background music systems, fire detection and evacuation systems, intruder alarm systems, surveillance systems (CCTV), building management systems, telephone and communication systems, access control and pay parking systems, data communication networks, conference systems, and pedestrian counter systems.
Electrical power
Electrical power distribution externally and in buildings is designed to meet safety and functional criteria in accordance with the relevant SANS standards, statutes and local authority by-laws. Reticulation is designed using the most suitable products from overhead lines, cables, busbars, wiring and wireways (conduits, powerskirting, trunking in floor or ceiling). Metering and sub-metering are arranged based on the most cost-effective tariffs. Power factor correction is recommended where this will result in further electricity cost savings.
Illumination
Artificial lighting is designed to meet statutory, functional and aesthetic requirements using a selection of general and task lights. Lighting may be designed for external (street and area lighting, security and sports lighting) or inside buildings. GIBB uses sophisticated computer software to optimise lighting designs.
Electronic systems
Modern buildings rely increasingly on electronics systems for communications, security, management and revenue. There is often a high degree of interfacing and coordination between different power and electronics systems to ensure correct building function under power failure or fire conditions, and to reduce electricity energy consumption. GIBB is able to provide independent, professional engineering services for most electronic systems used in buildings.
